Question

(a) What is meant by contraception? What are the different methods of contraception?
(b) What is done in the contraception method known as (i) vasectomy, and (ii) tubectomy?
(c) If a woman is using copper-T for contraception, will it protect her from sexually transmitted diseases?


Solution

(a) Contraception is defined as the prevention of pregnancy in females by preventing fertilisation. The barrier method, chemical method and surgical method are some of the methods of contraception.

(b) (i) The surgical method of birth control for men is called vasectomy, in which a small portion of the vas deferens is cut and their ends are sealed to prevent sperms from coming out.
(ii) The surgical method of birth control for women is called tubectomy, in which a portion of the oviducts are cut and their ends are ligated to prevent the release of eggs.

(c) No, using copper-T will not protect a woman from sexually transmitted diseases (STDs).
